Paragraph (b)

Operable with Low Vision and Limited or no Hearing

1. Individuals with low vision often also have hearing disabilities, especially older individuals. These persons cannot rely solely on audio access modes commonly used by people who are blind. Tactile strategies are still quite useful, although many older persons may not be familiar with Braille. The objective, therefore, is to maximize the number of people who can use their residual vision, combined with tactile senses, to operate a product.

2. Strategies for addressing this provision may include the following:

a. Make the information on the product easier to see. Use high-contrast print symbols and visual indicators, minimize glare on the display and control surfaces, provide adequate lighting, position controls near the items they control to make them easy to find, and use Arabic instead of Roman numerals.

b. The type-face and type-spacing used can greatly effect legibility. The spacing between letters should be approximately 1/16 the height of uppercase letters and the spacing should be uniform from one label to the next. Also, symbols can sometimes be used which are much more legible and understandable than fine print.

c. Where the display is dynamic, provide a means for the user to enlarge the display and to "freeze" it. In addition to making it easier to see, there are strategies which can be used to reduce the need to see things clearly in order to operate them.

d. A judicious use of color-coding, always redundant with other cues, is extremely helpful to persons with low vision. These cues should follow standard conventions, and can be used to reduce the need to read labels (or read labels more than the first time). In addition, all of the tactile strategies discussed under section 1193.41 (a) can also be used here.
